Professional installer is highly recommended. Coilovers are more expensive than springs but they allow the user to adjust the ride height at any time. This provides the car owner the ability to adjust the ride height depending on weather conditions, what wheels/rims are on the car, etc. During the winter you can raise your coilovers to gain more clearance. This reduces the likelihood of snow and ice contacting the undercarriage causing damage. During the summer you can lower the ride height. You can also adjust the damping on many coilovers. Having damping adjustment allows you to control the ride quality; softer or harder depending on what kind of driving you are doing. Our professional technicians do heavy research and development in testing car applications and fitments for our products. We also do rigorous testing on the strength, durability, as well as longevity of the material in order to make sure when the product arrives at the consumers end that its ready to go without worries.
